[teiid-issues] [JBoss JIRA] (TEIID-2584) Add management features to materialization

[Ramesh Reddy (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12801250#comment-12801250 ] 

Ramesh Reddy commented on TEIID-2584:
-------------------------------------

Per SteveH suggestion, added a "status" check such that when a materialization view is being accessed, it will issue a query like below to fetch the results of the materialized view

{code}
SELECT * FROM MAT_VIEW WHERE EXISTS (SELECT MVSTATUS(Valid, LoadState, OnErrorAction) FROM {statusTbl} WHERE VDBName=? AND VDBVersion=? AND SchemaName=? AND viewName = ?)
{code}

Where "MVSTATUS" is a system function, which based on the validity and LoadStatus carries out the "action" defined by OnErrorAction. Currently it code allows THROW_EXCEPTION, IGNORE actions.

> Currently Teiid supports internal and external materialization features. The internal is managed completely by the Teiid query engine along with the infinispan cache. 
> External materialization is completely unmanaged and left out to the user to manage it externally. This goals for this feature are unify the materialization logic for internal and external, such that both are managed similarly irrespective of the type of materialization chosen.
